Conversion C++ vers delphi
Bonjour,
J'ai un fichier dll créer avec Visual C++ 10 qui une fichier d'entête avec des fonctions exporter suivant:
- hHandle Initialize();
- int DeInitialize(hHandle H);
- Void OnProcessedFrame(hHandle H, Frames F);
Je traduit ce code en delphi 7, mais j'ai une blocage.
Les fonction initialize et deinitialize n'a pas de probleme sauf le fonction callBack OnProcessedFrame donne des erreurs en renvoie le parametre Frame F.
Ma question est: Comment on traduit correctement le parametre Frame en delphi 7.
J'ai mis en bas le code de Frame qui est dans l'entete C++.
En remarquant que Frame contient des array liste mais il renvoie sous forme de pointeur. Comment renvoie tableau array c++ en delphi 7?
